2 Application filed March 29, 1926. Serial No. 98,351.

This'invention relates to graphic instruments and has for an ob ect to prov de an mproved constructlon'wherein the writing or scribing instrument maybe moved to an operatlngposi'tlon or to aprotected and inoperative posltion.

Another, ob 'ect vide an instrument which may be used for member is readily movable from one position to another and is held firmly in place in either position, the parts being "so arranged that when in one position the writingmember is. covered and protected against injury while in the other position it is moved to a point where it may engage the article to receive the writing.

A further object, more specifically, is to provide an instrument wherein a sliding sleeve is positioned to carry ascribing member and is mounted to slide on a tube so that when in one position the scribing member is protected by the tube and when in the other the scribing member is projecting beyond the-tube ready for use.

In the accompanying drawing Figure 1 is a perspective vlew of an instrument. disclosing an embodiment of the invention. thesame being shown in use.

Figure 2 is a side view of the instrument shown in Figure 1, the parts being moved to an inoperative position. 7 v V Figure 3 is a sectional view through Figure 2, approximately on line Figure-4a lsan enlarged detail perspective view of the tube shown iniFigure 2. the same 1 embodying certain features of-the invention.

Figure 5 is a perspective view of the slide shown in Figure 2, the sameembodying certain features of the invention. 7

Referring to the accompanying drawing by numerals, 1 indicates the scribing memher which is shown as a pen but it mightbe a pencil or sharpened piece of metal. The scribing member 1s mounted as heremaften fully described on the slide 2 which is slidingly mounted on a tube-3. which tube is rigidly secured to the handle 4. The slide 2 is provided with a depending looped section '5 which is adapted to be engaged bv the thumband second fingerias shown in Figure 1 henthe device is in use, said portion 5 acting to compel the hand'to beproperly po-' sitioned in respect to the instrument and to also cause the instrument to be held ata proper angle in respect to the hand. This of the invention is to pro-e will have a tendency to tilt or compela cor- I rect holding of the instrument or in factfa correct holding of any pen or pencil The handle 4 may be Wood or any'desired' mater al and is secured to the tube 3 in anyfdesired manner, as for instance. by having portions 6 of the tube forced" into thefwood. The tube 3isfor1ned of sheet metal and when certain portions are forced intouthe handle 4, a burred formation is produced which will act in a certain sense as brads for holding'the parts firmly together. It is evident, however that small nails ,or' other securing means/could be provided without departing from the spirit of the invention.

The tube 3 is provided with a slot 7 for its,

full length exceptatthe outer end where the slot is covered byla ring 8 soldered or otherwise 'rigidlv'secured to the tube. This ring holds the slot open at one end while the fastening means 6 holds the slot open at the opposite end as well as secures the tube to the handle.v In addition. the edge 9 of ring 8 acts as an-abutment or stop for the slide 2 whereby it is limitedin its outward movement.

The slide 2 is preferably made. from a single piece of sheet metal and is bent with an arc-shaped section 10 merging into a strai ht section 11 which nroiects through tallic member. As shown in Fi ure 5. the

arc-shaped members 10 and 14 proiectpreferablv a short distance beyond tubular part 12 so that'when-the end 15 strilzes the shoulder 9 members 10 and 14 will pro iect a short distance bevond the tube 3 so that the pen or other instrument may properly function. 1

W h en, the devicei's in use the parts are" arranged or moved unt1l they will occupy substantially the position shown in Figure 1;

'When the deviceis not in use, the slide 2 is moved-back untilit assumes substantially I the position shown in Figure 2 which movelnent willca-use a ret'action of the instrument 1 until the same is wholly within the tube 3 and is protected thereby. This permits the instrument to be carried in apocket' or in any desired manner. The slide 2 is made of sheet metal and the parts are so sprung that the straight sections 11 and 13 press against the tube 3 at the slot 7 whereby. the-v slide 2 will remain in any position in whichit is placed.

What I claim is:

1'. A graphic instrument comprising, a tube having-.a slot, a handle extendingfrom said tubular member at One end, a stop near the oppositeend, a slide mounted on said tube formed'with-a loopedradially extending portion acting as a thumb and finger grlp efor causing the instrument to be" cor.- rectly positionedin the hand when in use, and-means.extending from said slide pro-j ectingthrough said slot and acting as a scribm instrument grip.

2 A graphic instrument comprising a tubularmember having. a longitudially positioned slot, a handle connected withv said tubular member atone end, means at the opp0site.endacting as a stop, a slide formed with a tubular portion, a looped thumb and finger grip, and a pair of pen gripping eX- tensions, said gripping extensions projecting through said slot for gripping a pen Within said tubular member and said looped thumb and finger grip projecting radially from the tubular memberifor causing the hand to be properly positioned when using the device, said pen gripping extensions being movable into and out of said tubular member as the slide is moved.

3. A graphic instrument comprising a tube having a longitudinally positioned slot, a handle extending from said tube at one end, a stop near the opposite end, ajslideimount ed on the tube formed with a tubular portion and a radially extending looped portion, said tubular portion being formed with inwardly extending arc-shaped. clamping members, said clamping members extending through said slot and positioned for clamping a. scribing instrument withinpsaid tube, said radially extending portion dependingvan appres ciable. distance from the tube and aoting as thumb and finger guides.
